first, are you north of I10 or south? some may not be aware of why I ask, but as you know the heat and humidity . now for your question, have the same situation as you I have found an IWB (crossbreed) to wok very well and stays Concealed with just a tee shirt.

I had a pocket clip on my PF9. It was comfortable, and very concealed.

Second, I have a Crossbreed, and love it... That being said, I will be ordering my next iwb from Theis holsters. Theis makes an almost identical holster to Crossbreed, but they are considerably cheaper. Also, there have been some recent posts regarding Crossbreed slipping in quality.

There are leather vests that have concealed carry pockets inside available. I ride too and I think it would be very difficult to keep a handgun covered while out on the road. When I get my permit I am going to try the vest route, I usually wear one anyway.

I dont know if ur state allows open carry but i use a fobus elite concealed with my glock 30 when i ride sometimes you can see a little bit of my gun but open carry is legal here so i dont worry if it slips out a little

When riding I carry left handed. Usually a G36 open carry, although times I will conceal.
It would have to be an extreme situation when I would actually shoot from my bike, moving or stopped, but I have trained that way. Shooting left handed gives me control of the front brakes and throttle. I don't need the clutch lever for stopping, starting or changing gears. I usually carry left side hip holster in the 8-9 o'clock position. Training included shooting with riding gloves and helmet.

I can draw with my left hand from my right hand carry rig, normally. But trying to get it out when wearing tight leather and bent over the tank of a Ninja presents a challenge carrying left hand overcomes with ease. Although I normally carry right handed, I was born a lefty and shoot either hand without much difference.

A few years back, I came up on a group of riders pulled off and searching the field just off the road. I joined them. Turns out one of the kids took a low side and his Glock came out of the holster. He was fine, his bike was fine, his Glock was fine, but it took a dozen riders about 30 minutes to finally find his Glock tucked under a cactus! There were a few scratches on the rider, the bike and the Glock, and he learned a lesson about holster retention. Just something you might want to consider, if you haven't already thought about it, when selecting your carry method.
